The transfer of an electron from an atom of _ ionization energy to another atom with _ electron affinity was called an ionic bond by Lewis.
Correct answer: C. Low, High
- A. High, Low
- B. Low, Low
- C. Low, High
- D. High, High
Explanation
In an ionic bond, the metal atom transfers electrons to the non-metal atom. A metal atom, by nature, has the property of having low ionization energy (I.E.) compared to a non-metal atom as it has a tendency to lose electrons. Similarly, a non-metal atom by nature has a high electron affinity (E.A.) compared to a metal atom as it has a tendency to gain electrons. Hence, "low I.E. and high E.A." will be the correct answer here.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
